Liquid crystal thermography supported by PIV and DII as modern and unique tools for technical and biomedical research and diagnosis – mini review

Liquid Crystals Thermography, Particle Image Velocimetry, Infrared Imaging Thermography and Digital Infrared Imaging have been successfully used in non-intrusive technical, industrial and biomedical studies and applications. These four tools (based on the desktop computers) have come together during the past two decades to produce a powerful advanced experimental technique as a judgment of quality of information that cannot be obtained from any other imaging procedure. A brief summary of the history of this technique is reviewed, principal methods and tools are described and some examples are presented mostly from our own research. Automated data evaluation allows us to determine the heat and flow visualization and locate the area of suspicious tissue in the human body. Anyway with this objective, a relatively new experimental technique has been developed and applied to the study of heat and mass transfer and for biomedical diagnosis.
